The present invention provides an optical recording material allows for obtaining excellent recording signal properties even at high-speed recording and is excellent in durability in both a single-sided single layer optical recording medium and a single-sided two-layer optical recording medium having a first recording layer and a second recording layer. A dielectric spacer layer is disposed between a nanoantenna layer and a metallic ground plane layer. The first fixing component is adapted for being mounted to the supporting base and has a first basic plate adapted for carrying the laptop computer.
